An uncommon example with wonderful pokerwork design on both sides of the headrest. The name that appears on the headrest appears to be "CALTEX".

"Objects among the Zulu were personal. Some were made expressly for their owners, and would become, in time, closely linked with that person's identity by association and a lifetime's use. A headrest, for example, may have been brought by a bride from her parent's homestead as a betrothal gift to her husband's homestead. The headrest would be regarded as a link to her father's spirit and the amadlozi, her forebears' spirits." - Karl Nel, The Art of Southeast Africa
